Posts in the AI Agent Funding series
Vals AI closes a $40M Series A led by Andreessen Horowitz at a $400M valuation. The round signals that VCs are starting to treat 'independent AI evaluation' as essential trust-layer infrastructure for the AI economy — not a nice-to-have leaderboard site.
Wispr closed a $280M Series B led by Menlo Ventures at a $2B valuation (up ~3x from $700M in November 2025). This round signals VCs betting that voice will replace text input as the next human-computer interface entry point.
Higgsfield closed a $400M Series B led by DST Global, reaching a $5.4B valuation (up over 4x from $1.3B in 8 months). The capital signals that enterprise AI video generation demand is rapidly displacing traditional agency-led production workflows.
Trajectory closes a $40M Series A led by Sequoia Capital at a $300M valuation (2.6x increase from Seed just 3 months prior). The round signals that the Agent optimization battlefield is shifting from 'swap in a bigger model' to 'let deployed Agents learn continuously from real-world usage signals.'
DEEP.FINE closed a ₩10B (~$6.6M) Series B led by Hyosung Ventures. The round signals that the next AI Agent battleground is extending beyond chat windows into heavy industry — smart glasses, sensors, and physical workflows on factory floors.
Prevalent AI closes a $22M first institutional round led by Integrity Growth Partners. The deal shows that 'prove the market first, raise later' still works in the agentic AI era — while most startups burn VC money searching for PMF, a company that bootstrapped for 9 years and already serves large enterprises chose to raise only when agentic AI needs it most.
Callosum closes a $100M seed round led by Atomico, valuation undisclosed. The bet: the agent cost bottleneck is not the model itself but cramming every step into the same GPU. As inference spending eats over half of AI-native companies' revenue, the routing layer's value expands from model selection to chip selection.
Twin1 AI closed a $20M seed round co-led by Bessemer Venture Partners, Tribeca Venture Partners, and Aramco Ventures, with valuation undisclosed. The bet: the atomic unit of enterprise knowledge isn't the document — it's the person. While every Agent startup races to plug into document repositories, Twin1 goes after the context that lives in people's heads and was never written down.
Rundoo closes a $30M Series B led by Battery Ventures, with Bessemer and CRV following on, bringing total funding to $48M. The bet isn't on an 'AI add-on layer' — it's on using an Agent to outright replace the legacy system-of-record that independent retailers have relied on for decades.
Stability AI closed a $76M Series B led jointly by Universal Music, Warner Music, Sony Music, and EA, bringing total funding to $232M. It is the first AI company to secure direct equity investment from all three major record labels simultaneously — signaling that copyright holders are shifting from 'sue AI' to 'invest in AI.'
Runable raised a $21M Series A co-led by Susquehanna Venture Capital and Nexus Venture Partners, at a $65M post-money valuation. The Bengaluru startup's agent doesn't just build your website or app — it also runs your ads, posts to social, and handles SEO, folding 'build' and 'grow' into a single agent.
Instinct raised a $250M Series B co-led by Index Ventures and Benchmark at a $2.5B valuation. Still in invite-only beta, the personal AI assistant startup uses a pure-software interface (SMS and phone calls) to sidestep the hardware failures of Rabbit and Humane.
Deep Cogito raised a $43M Series A led by TQ Ventures, with Benchmark, Nexus Venture Partners, and Zscaler among participants, bringing total funding past $56M. The bet isn't on the next frontier model — it's on whether post-training itself can become a standalone, sellable business.
Keenable came out of stealth with a $26M seed round led by Accel, with Conviction Partners participating. The bet isn't 'search that beats Google' — it's that AI agents query the web in a fundamentally different pattern than humans do, and need retrieval infrastructure designed from scratch around that.
Just four months after coming out of stealth, Onyx Security raised a $113M Series B led by Bessemer Venture Partners at roughly a $640M valuation. The bet: a control layer that watches every step of an agent's reasoning and intercepts actions before they take effect is the next generation of security infrastructure.
Zenity closed a $125M Series C led by Norwest Venture Partners, with SoftBank Vision Fund 2, Hitachi, and LG Technology Ventures joining. Norwest's thesis: the agent is the new perimeter — traditional network-boundary security no longer works against autonomous agents, and a governance platform has to be built for agents from the ground up.
Owner closed a $240M Series D led by Growth Equity at Goldman Sachs Alternatives, pushing its valuation to $2.3B — more than double the $1B it hit at Series C. This is traditional growth equity making its first big bet on vertical AI agents that run an entire industry's day-to-day operations, not just a general-purpose assistant.
AIR Security exited stealth with two seed rounds totaling $50M — $10M led by Sequoia, then $40M led by Greenoaks. This is VC money betting directly on founder pedigree and timing in the unproven 'AI agent supply-chain security' niche, rather than waiting for a Series-A-grade growth curve first.
Tripo AI (parent company VAST) closed a combined Series B and Series B+ round worth roughly RMB 3 billion (about $420M), led by MPCi with heavy follow-on from gaming and entertainment strategic investors. This is China's market treating 3D-native foundation models as their own infrastructure category worth a big bet, not just a stopgap built by bolting 2D generative models onto 3D.
Wonderful closed a $550M Series C led by Insight Partners, with Salesforce making its first investment in the company, at a $5B valuation — 2.5x its $2B Series B mark from less than six months ago. This is VCs betting on a unified enterprise-wide 'AI operating system' layer, rather than continuing to fund a pile of disconnected point agents.
Capacity closed a Series E of more than $54M, bringing total funding past $159M, right after crossing $100M ARR in June — a 20x increase in 3.5 years. This is enterprises consolidating budgets from scattered point AI-support tools into a single platform, and Capacity is betting its unified 'train once, use everywhere' knowledge layer beats purpose-built, siloed agents.
HiddenLayer closed a $100M Series B led by Delta-v Capital, with Morgan Stanley, Microsoft's M12, and Booz Allen Ventures joining. ARR grew more than 10x in a year. This round signals AI agent security expanding from 'monitor agent behavior' to a new front: protecting coding agents that write and ship their own code.
Conveo closed a $50M Series A led by Balderton Capital, with DST Global Partners and Y Combinator among the backers, bringing total funding to $55.8M. This round signals market research — a traditionally slow, project-based industry — being rebuilt as infrastructure where AI agents talk to consumers continuously, rather than being outsourced to research firms for one-off studies.
Gimlet Labs closed a $300M Series B led by Andreessen Horowitz at a $3B valuation — 7.5x its $400M Series A mark from six months earlier. This is VCs betting that the layer coordinating multiple chip architectures, not any single chip, is the next bottleneck to solve for agentic AI inference.
